6 Claims. -.1

This invention relates to window shades of the type in which the edges are substantially sealed in relation to the frame of a window in which the shade is positioned, and in particular a window shade having enlarged hems or tunnels providing sleeves at the sides and in which eccentrically mounted pins extended through said tunnels are rotated to clamp the edges of the shade against the inner surfaces at the sides of the window frame.

The purpose of this invention is to provide means for continuously sealing the edges of a window shade in relation to a window frame in which the shade is positioned.

Various attempts have been made to hold the edges of window shades to prevent rays of light and also circulation of air passing through the window, however, owing to the material of which window shades are formed it is diflicult to grip the edges without tearing the shade when excessive loads, such as resulting from high winds, contact the shade. With this thought in mind this invention contemplates forming continuous tunnels on the edges of window shades whereby the gripping or holding load is applied continuously throughout the length of the shade and wherein the holding means is accomplished by clamping the shade against the inner surface of a window frame.

The object of this invention is, therefore, to

provide an improved window shade mounting wherein eccentrically mounted rods extended through tunnels at the sides of a wind-ow shade are actuated to retain the shade in clamping relation with a window frame. Another object of the invention is to provide means for mounting a window shade having tunnels on the edges whereby the tunnels are adapted to be rolled on a shade roller in the upper part of the window.

A further object of the invention is to provide an improved shade mounting wherein a shade is held continuously along the side edges and in which the mounting is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a window shade mounting having a conventional shade roller encased in a housing at the upper end of a window frame with a shade on the roller in which the shade is provided with continuous tunnels at the sides and across the lower end and in which the edges of the shade are held with eccentrically mounted pins which extend upwardly into the tunnels, the upper ends of the pins having eccentrically positioned extensions of reduced diameter and the lower ends having arms connected through springs to a lever pivotally mounted on the window sill.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure 1 is a front elevational view illustrating a window having the improved weather shade installed therein showing the shade drawn downwardly to a point spaced from the window sill.

Figure 2 is a similar view showing the shade moved upwardly and with the eccentric pins turned so that the shade is released from clamping relation with the sides of the window frame.

Figure 11 is a detail showing a shade roller clip or bracket positioned in a recess in the window frame.

Figure 12 is a longitudinal section taken on line l2|2 of Fig. 11 also illustrating the recess with the shade holding clip therein.

Figure 13 is a sectional plan through the lower part of the window, taken substantially at the point indicated by the line 3-3 on Figure l, illustrating a modification wherein the operating elements of the pins on which the shade slides are incorporated in the window sill.

Figure 14 is a detail showing a section through the window sill of the design shown in Figure 13. Referring now to the drawings wherein like reference characters denote corresponding parts the improved weather shade of this invention includes a shade l having sleeves or tunnels H and I2 at the sides with a tunnel I3, for a window stick, extended across the lower end, eccentric pins l4 and I5, pivotally mounted on studs I5 on bearing plates said eccentric pins having noneccentric pins l8 extended from their upper ends, rollers l9 and positioned to engage side surfaces of the pins l8 for supporting the upper ends of the pins, and a hand lever 2| pivotally mounted by a pin 22 on the window sill 23 and connected to arms 24 and 25 extended from the lower ends of the pins I4 and I5 by rods 26 and 21 with springs 28 and 29 extended around the rods and positioned to urge the arms 24 and 25 outwardly away from the center wherein sections of the pins l4 and I5 clamp the edges of the tunnels II and I2 against the inner surfaces of a window frame 30.

The pins M and i5 are provided with eccentrically positioned bores 3| and the studs l6 extend into the lower, ends of the bores whereby as the pins l4 and I5 are rotated on the bearing plates If the larger radius clamps sections of the pins against the inner surfaces of the side members of the window frame.

The window sill 23 is provided with studs 32 and 33 against which the ends of the springs 28 and 29 are positioned and with the parts released as illustrated in Fig. 3 the springs urge the arms 24 and 25 outwardly away from the center of the sash, to the position shown in Fig. 3 whereby the sections of the pins 4 and IS, on the larger radius, are urged into clamping relation with the inner surfaces of the window frame. When it is desired to release the window shade the hand. lever 2| is moved to the left thereby drawing the arms 24 and 25 inwardly with the pins I4 and I5 turned to the position shown in Fig. 2 whereby the sides of the shade are released from clamping relation with the inner surfaces of the window frame.

The rollers l9 and 29, between the eccentrically positioned pins I8 at the upper ends of the pins l4 and I5 are positioned or journaled on shanks 34 and 35 of screws 36 and 31, respectively and the rollers are positioned, with one at a higher elevation than the other, as illustrated in Fig. 4, to facilitate the hems or tunnels at the edges of the shade passing between the rollers and. also to permit the tunnels being flattened as the shade passes around a shade roller 38 at the upper end of the window frame.

The rollers |9 and 20 hold the sections l8 of the pins in alignment with studs IE on the bearing plates H, the bearing plates being held by screws 39 to the window sill and the plates being positioned in slots 49, as shown in Fig. 4.

The ends of the shade roller 38 extend into recesses 4| in the sides of the window frame with pins 42 at the ends of the roller held in clips 43 on base plates 44 which are mounted in the recesses 4| with brads 45 or the like. The clips 43 are provided with slots 46 in which the pins 42 are positioned.

The shade roller is preferably covered with a plate 4'! that is secured to the window frame with fasteners 48.

The bearing plates I! may be replaced with similar bearing plates 49, as shown in Fig. 10.. the plate 49 being provided with studs 5|], similar to the studs i6 and with elongated slots 5| through which screws similar to the screws 39 4 may be placed whereby the eccentrics of the pins l4 and I5 are readily adjustable.

With the parts mounted in this manner the hand lever 2| is turned on the pivot 22 whereby the rods 26 and 21 draw the arms 24 and 25 toward the center moving the sectionsof the pins l4 and I5 on the large radius through an angle of substantially degrees whereby the surfaces of the pins move away from the sides of the window frame to the positions illustrated in Fig. 2 and. the shade is released so that it may be moved upwardly and downwardly. When the shade is in the desired position the lever 2| is released and the springs 28 and 29 urge the arms 24 and 25 outwardly whereby the sections of the pins l4 and I5 on the large radius clamp the edges of the shade against the inner surfaces of the window frame.

With the rollers |9 and 20 positioned as illustrated in Figs. 4 and 5 the tunnels at the sides of the window shade collapse and bulge outwardly through the rollers whereby the tunnels are flattened as the shade passes over the shade roller 38.

The operating parts including the lever 2|, springs 28 and 29 and cables 26 and 2'! are protected by a cover 52, as shown in Figure 4. The cover is spaced above the window sill by a flange 53 at the front.

In Figures 13 and 14 the operating parts including the lever 54, similar to the lever 2|, springs 55 and 55, and cables 51 and 58 are incorporated in a window frame 59 below'a sill 6|! and pins BI and 62 similar to the pins l4 and I5 extend upwardly through openings in the window sill. By this means the operating parts are hid.- den and the parts are actuated by an extended end 63 of the lever 54, the end 53 of which extends through a slot 64 in the window frame. The pins 5| and 62 are provided with extensions 65, to which the operating parts are connected as shown in Figure 14.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
